Definitions

  • the invention relates to a mowing apparatus for harvesting large-sized plants. Furthermore, the present invention relates to a method for harvesting large-grown plants using the device according to the invention.
  • high-growth plants include, for example, trees such as short-rotation shrubs and also shrubs and stalky plants such as maize.
  • trees such as short-rotation shrubs and also shrubs and stalky plants such as maize.
  • Harvest is understood in the context of the present invention, the cutting of the plants and the processing of the cut plants to wood chips (bulk material technology).
  • center of a plant When the term “center” of a plant is used in the context of the present invention, it is assumed that the plant is upright, ie standing, and “center” denotes the area corresponding to half the height of growth of the plant.
  • a typical example of this is the harvesting of trees from the standing stock in short rotation plantations.
  • cut plants are then placed in an approximately horizontal position, from which they are fed by means of special rotating lifting arms and horizontally arranged rollers via other feed rollers of the actual chopper drum in the forage harvester.
  • a disadvantage of this solution are the very high technical costs, which lead to high machine masses and crop costs.
  • the cutting of the trees takes place primarily with circular saw blades whose axis of rotation is arranged approximately vertically.
  • the trees are brought after cutting in an approximately horizontal position and then fed by means of special recording elements of the crusher (chopper drum, screw).
  • Characteristic of this harvesting principle is that the plants are bent before and during the cutting of the rootstock in the direction of travel. For large plants with a stronger trunk thus creating the risk of breaking off or tearing out the entire root ball from the soil.
  • the trees remain in an approximately vertical orientation and are fed for comminution by means of special feed elements such as drums or screws.
  • a device which already has an additional feed assembly, which is intended to effect an improved feed in cooperation with a cutting disc.
  • the feed assembly consists of a paired worm-roller combination that is approximately over the axis of rotation of the cutting disc.
  • an improved supply of cut plants is to be ensured.
  • the cutting is done with special cutting elements on the outer circumference of an inclined chopping disc are arranged.
  • the chopping disc is provided with radially arranged chopping knives.
  • the hackford has slots and is therefore permeable, so that the wood chips can be passed into a cavity below.
  • the chopping disc is additionally occupied on its underside with throwing blades, which promote the wood chips due to the centrifugal force from the cavity to the outside through a discharge opening. From there, the chips are taken over by another conveyor such as a belt conveyor. From operational experience, it is known that the safe feeding of large in-line plants requires further support and measures of clustering at the plant's center of gravity. Furthermore, the mechanical engineering implementation in a concrete harvester associated with considerable technical expenses (eg, the storage and drive the Hackfit).
  • rotatable helical feed elements which capture the plant approximately in the middle in a first step, feed and fix. This is to prevent the plants from falling over after cutting off the rootstock.
  • the plants After cutting with two paired circular saw blades, the plants are detected in the lower part of two counterrotating augers, which turn into rollers at the end. These rollers capture the plants and promote them in the direction of the chopping disc, over which a counter-blade is arranged. Due to the effect of the chopping knives and by means of additional throwing blades, the wood chips are ejected from the housing.
  • a disadvantage of this solution is the considerable technical effort for the numerous rotating assemblies for the supply, the cutting, the feeder, the feed, the crushing and the Gutaussch.
  • ten rotatable functional assemblies consisting of two helical feed helices, two circular saw blades, two augers, two pull-in and press rollers, a hack rotor, and an ejection unit are required.
  • Characteristic of the prior art devices discussed above is the large number of assemblies required. This is particularly disadvantageous in terms of manufacturing costs and maintenance requirements. Furthermore, it should be noted that the weight of the devices increases with the number of required assemblies. Of course, this also means that an associated higher weight is associated with a higher energy consumption in the operation of the device, which has a negative effect on the operating costs and is disadvantageous in terms of the environment.
  • the invention is therefore based on the object to overcome the disadvantages of the prior art.
  • the object of the present invention is achieved by the provision of a simple, compact and comparatively lightweight device, which is able to cut approximately vertically from the ground protruding to be harvested plants from a horizontal movement of the device and the plants in a second step in a downwardly directed Moves to bring them to shredding. It is essential to the invention that in direct connection to the comminution of the plant, the conveyance of the shredded material obtained to the transport container takes place without further driven assemblies. For the shredding of the plants and the promotion for removal so no additional assemblies are needed.
  • the promotion of wood chips according to the invention is carried out directly to a transport container, so that no interruption of the material flow of wood chips takes place within the device. This eliminates the need to use additional, driven conveyor assemblies.
  • the construction of the device according to the invention due to the reduction of the number of modules considerably simpler and can also be made much more compact, because there is no need for additional assemblies for the promotion of wood chips.
  • the device according to the invention therefore has a much lower weight compared to devices of the prior art.
